This week the puzzle can be solved both as an Edge Sums Sudoku and as a Frame Sudoku. I have used them together in a puzzle, but now they're separate puzzles. I tried for a while to get both puzzles to be solvable without any givens. I only had a limited range of sums to work with, which caused some issue. Edge Sums was the hardest to get unique in this combination as Frame Sudoku gives you the option of creating a useful implied sum. Eventually I compromised by putting two givens in the middle. The Edge Sums puzzle is the easier of the two in this set.
